Hey there, I'm far from a Canadian but I jinxed this threat on US forums.

GFS and GEM are in scary agreement to a cutter moving through the system in the timeframe.

SOI drops big in the timeframe, shows potential for a storm.

The weather network had a video of Chris St Clair discussing many things with a meteorologist. One thing they touched on was a January thaw close to the end of January. Their website forecast doesn’t show anything about that. Confusing. What you’re talking about here may be a major thaw. Would this be what Chris was eluding too? And if so does anyone see this in the models. I know it’s a long way out.

Another thaw? We just had one, didn't we? It was 13 degrees here last week in S. Ont rolleyes.gif

Well thanks for starting a thread. EPS has been hinting at major above average anomalies coming in at this time so it’s no surprise this is a cutter. This one isn’t shifting SE enough to give snow to anyone in this forums region so you won’t be jinxing it for us lol.

On a separate note the 00z ECM has another storm after this one at the end of its run and that one is more on the cold side look atm. As usual we’ll watch them all.

Models have been hinting at a warm spell coming up this weekend and into Monday of next week. The cutter seems to come on Monday with some 2-3C weather in store for the weekend.

At this point models seem to show rain as far north as North Bay with highs in the 5-8C range for S/E ON for next Monday.

According to JB, that was the "pre-thaw", with the real one to follow. But don't worry, he also says winter will return in February and March. Anyhow, here's what the Jan 16th 12Z GFS text prog has to say. Note that that the storm is at the extreme end of of the forecast range, so there may be more precip beyond hour 144. I'm only doing London/Waterloo/Hamilton this run, because the storm still hasn't hit the other sites fully by hour 144.

Can the original poster please edit the title to start on the 21st, rather than the 22nd?

Thanks for info! Interesting what JB tweeted. I hope he is right about more winter to come. This winter did start pretty good but I definitely hope for more and enough of these thaws! I know they are par for the course but I am still not a fan. But I guess what true snowlover is?

Looks like it's going to be a long drawn out event. Note that rain probably continues past hour 144. That's simply as far as the forecast goes. I'll add more easterly sites as they get within range of the forecast.

Looks like it's going to be a long drawn out event. Note that rain probably continues past hour 144. That's simply as far as the forecast goes. I'll add more easterly sites as they get within range of the forecast.

24+ hours of rain, totalling approximately 2/3rd of an inch (16 mm) is probably why.
